Dramatic discovery links Stonehenge to its original site – in Wales

Find backs theory that bluestones first stood at Waun Mawn before being dragged 140 miles to Wiltshire

An ancient myth about Stonehenge, first recorded 900 years ago, tells of the wizard Merlin leading men to Ireland to capture a magical stone circle called the Giants' Dance and rebuilding it in England as a memorial to the dead.

Geoffrey of Monmouth's account had been dismissed, partly because he was wrong on other historical facts, although the bluestones of the monument came from a region of Wales that was considered Irish territory in his day.
